HRA 110 Handwheel Adapter
The HRA 110 handwheel adapter enables you to connect two or three HR 150 panel-mounted
handwheels to the TNC. The first and second handwheels are permanently assigned to the X and Y
axes. The third handwheel can be assigned to the X, Y, Z or IVth axis, either by a step switch
(option) or with MP7645 (see “Machine Integration”).
